[Q] What to do Against battery drain?

I now have one week to the Nexus One bought secondhand. It suits me perfectly stand alone I have a little trouble with the battery life of the phone. Morning when the phone is 100% and I come out of school (14:30 hours) the battery is still around 20%. I find this a bit short. Ok, I'll use him at school (bit Internet, twitter refreshes every 9 minutes)
There is an automatic task killer, and that helps a bit but I think there are about 80% after 8 hours battery life is a bit much. Me internet is also constantly and I really like to keep.
The battery is probably not because I've got 2 batteries and they both give the same result.
Anyone have any idea what I can do?
I've been a bit inet searched but not really found anything. I did see somewhere a separate battery behind the phone, but I'm not waiting because that makes him a bit heavier and uglier.

10% per hour is pretty poor battery life. Are you running stock Android? 3rd party firmwares can give you much better battery life (the latest versions of CyanogenMod are using less than 1% per hour when fully idle).
But there are things you can check. Have you looked in Settings -> About phone -> Battery usage? If you are using Gingerbread and you look at the graph, if there is a solid line (or mostly solid) next to the "awake" portion, it means that your phone isn't properly entering its low powered state. Download spare parts from the market and check out partial wake usage under the battery history section of that app.

Please post your screen on time value from the battery menu so we can see how long your screen is on.

I would say to go and disable background data. Disabling this will definitely improve your battery life. Of course, you aren't going to get you twitter updates but aside from that, the battery life should improve.

While it is true that battery life would improve if Background Data was disabled (or limited via a program like Juice Defender), it doesn't take into account his actual problem. Unless it is a ton of apps constantly downloading that is keeping his battery usage in the toilet, this will only yield a slight improvement. I believe the cause is is an app (or apps) that prevent his phone from entering the low powered sleep state.
I don't know what stock Android gets from completely idle use (haven't run it since July last year), but a basic CyanogenMod install would sip between 1-2% per hour with the latest stable and the latest nightlies, some are reporting 1% every 2-3 hours when the phone is left alone (due to a fix that lets the microphones go into a deep sleep state).

Twitter refreshing every 9 minutes can not be helping, that said I doubt that's your entire issue but reducing the refresh rate should help quite a bit.

If you bought it used, it could be a bum battery. Not sure i know what apps work best to find out that info. Anybody?

The battery app in my sig is the only one that reads the chip inside your battery to tell if it's legit or not, what the battery age is, etc. Needs root to work though.

You can also get Battery Left from the Marketplace and when it gets calibrated it gives you a time until death number and some other features.

[Q] Battery life... Issue~

Hey guys! About 5 days ago I got my self a new HTC one (Dev, unlocked)~
Info: I'm running the latest Trick-Droid Rom, with Juice Defender(Free: Says i'm getting 112% battery life from it), Greenify, and Nova launcher~ And my case can sometimes run a little hot, something like 1C too at most 3C above no case temps.
Right now i'm getting about 5 hours and 20 minutes of web-browsing time on my battery, and with all these "Optimizing" apps... And the high reviews of the HTC one's Battery, i'm wondering if might have an issue on my hands?
I know I have not given enough info for anyone to give a diagnosis, I just want to know if I need to start digging for leaks!

I'm not using any battery saving apps or anything like that, I'm all stock, I have everything on except finance stocks and stock weather, I do a lot of web browsing, texting, music and that's about it...a few calls here and there. You may just need to give it a few more charge cycles...I don't believe in all those battery "saving" apps or "optimizing" apps.
Get "wake lock detect" and "better battery stats" to determine what's going on.
And my battery life isn't as great as some people's here, but it's pretty awesome to me.

I spent about an hour testing stuff... I found a major drain in the form of SH (Shell) stuck in some run away process, after deleting Storage/Bin/SH 3 or 4 times it seems to have fixed it self~
I think I will best sending in the bug too *TrickDroid* to see if they can get it fixed.... Deleting the SH file has made some small issues pop up from time to time~

Is this okay? Or is the performance low?

That's decent, 4-5 hours of screen time seems to be the average.

How I am getting good battery life: A simple guide with some links and stuff!

I see a lot of people complaining about battery life, myself included. I have tried just about every ROM there is and used all the battery saving apps and I think I've found a winning combination that will leave you with a fast phone and good screen on/off battery life. My stats so far today are 8 hours off the charger with 1 hr 30 mins SOT and still 80% battery left and that's shifting between my work WiFi which has many access points and causes WLAN_RX wakelocks and the crappy signal around this area.
I use the phone for general stuff like browsing the web, playing the odd 2D game whilst bored and push notifications from various social networking apps and I have been addicted to achieving 7+ hours of SOT over 2 days since I owned a Galaxy S1 many years ago. Instead of writing a crazy guide I'll just keep this thread simple and post my current configuration that is giving me good battery life:
- BOE2 bootloader, modem and ROM (I'm using Nameless ROM v2 for 910G)
- Roughly 25% brightness, all sync on, location @ GPS only (High Accuracy only when using Maps)
- Followed THIS GUIDE very closely which gives amazing deep sleep and still get notifications with the Push Notification Fixer app
- Uninstalled Facebook and Messenger and use Tinfoil with Pushbullet and the RSS Feed and set to open Tinfoil when I get a notification: Here's how to do that
- Discharge fully to 0% and then turn on again to make sure fully dead, then charge to 100% to calibrate battery
Wallah! You should get good battery life now provided you use the phone for the same things I do. It's that easy!

You need to be rooted for most of that thread don't you? I need my banking app from time to time so I can't root. Gutted!
Joe

Thank you for taking the time to write this up, but you should mention in the thread title that you need to be rooted. Thanks anyways though. I'm not the type to root. If Samsung can't deliver a good product for the $800 device they made, the device should be returned (which will be my case if the 5.1.1 update doesn't come in July or it doesn't fix the issues I'm having with this device).

Fully discharging a Li-Ion battery is not healthy for the long term life of the battery.
When will the myth of "re-calibrating" a battery finally die?!?
http://batteryuniversity.com/learn/article/how_to_prolong_lithium_based_batteries
Similar to a mechanical device that wears out faster with heavy use, so also does the depth of discharge (DoD) determine the cycle count. The shorter the discharge (low DoD), the longer the battery will last. If at all possible, avoid full discharges and charge the battery more often between uses. Partial discharge on Li-ion is fine. There is no memory and the battery does not need periodic full discharge cycles to prolong life.

Thanks for the guide, and I'm not sure why anyone on XDA would not be rooted tbf

Smartphone batteries haven't needed to be calibrated in years. The only time you ever had to "calibrate" your battery was when your phone would sit at either 5% or 1% for hours before dying.
Even then you were calibrating your phones interpretation of the battery voltage levels, not the battery itself. Unless I'm very much mistaken battery charging is handled by integrated hardware, not software.
As a software bug overcharging a Li-Po is dangerous and completely avoidable

Most of the software needed on those guide required exposed.. My question is does amplify, greenify boost, and powernap works on touchwiz lollipop? Also does the current xposed works stably for now?

I have no battery issues. Got 2 x 4500mah from chima as well.

Thanks for sharing this info just have one question I see from some of your other posts that you have used other roms is there much difference in battery between tw roms to cm roms
Thanks

Huh? Never had a problem running official apps from two different banks.

I'm finding TW to be slightly better on battery under my circumstances - which consist of terrible signal fluctuation and rx_wlan wakelocks due to so many wireless arrays at work - however I will probably go back to CM12.1 soon or wait for Android M developer preview to be ported to Note 4 (fingers crossed) as I just love how stock and minimalistic everything is on stock droid CM and AOSP and it seems to be a lot snappier when combined with L-Speed mod.

They fit with the original note cover. And they last a bit longer then original battery.

I bought 1 as well & I get about 3 more hours. .... with the same use as with the original battery !!!!! Definitely worth it, ,, even if its only 3 hours

Great battery life

Now imagine with root using Greenify at least to have the apps hibernate and not wake up until you open them to use.

Greenify was giving me issues. Causing my phone ui to constantly crash. Making my phone very unresponsive. I had to do a factory reset to get it to worknormal again.

wait really? hmm you must have greenified something wrong perhaps. i have never ever experienced that issue whatsoever with it with my G4.

Greenify never helped me much and always made the phones I've had it on act kinda wonky.
On somewhat light usage days I've been going to bed with the phone off the charger for 18 hours and at over 50%
I'm impressed with the G4 battery life so far, even with heavy usage for me I'm getting at least a day.

What are the most efficent Roms for T-Mobile's Note4 ?

I've been flashing like crazy to find the best Rom for battery life but still haven't found one that gives me 4 hours or more screen on time. The most i've gotten out of my device is 3.5 hours screen on time.
I really would appreciate any kind of suggestion. THANKS

FireKat (kitkat) and Poprocks (lollipop). Follow the directions exactly and use his second post for how to make it run. Keep in mind it takes 3-5 days to settle in before you get the best SOT.

depends on what kind of experience your looking for, if you want the note 4 style launcher and icons i would say poprocks for sure, but if your looking for the note 5 launcher and icons with a slight addition to speed i would go with the new 5.1.1 roms, im using tekhds rom and getting about 6 hour sot

I've used firekat and was only getting around 2-3hr SOT, google play services wakelocks were destroying my battery life and for some reason the wakelock mod didn't help either. Decided to check out lollipop and got Tekxodus 5.1.1, has been working great, very fast and responsive and now SOT 3-4hrs, still wish I could get the 9hr SOT others get

battery life these days is more of the quality of the battery you get, the only reason some people get 6 hours and some people get 3 is generally because not all batteries are created equal, there are obviously some steps you can take to increase battery life but that takes more time to and effort to setup as it requires nitpicking at the rom itself and other various apps to save battery life

Actually I did try different batteries, Samsung and Anker...

I'm not talking about the brand I'm talking about the specific battery itself, you can have one battery from Samsung be 6 hours and one be 3

FireKat ank4, Xposed with amplify and autostarts did the trick for me.
I went from struggling to get to 3 hours of SOT, to almost always exceeding 5 hours. The NLPWakeLock was KILLING me. I mulled over installing Xposed but there really isn't any way around it. It's the only way to kill that wakelock.
After installing Xposed and amplify to kill the NLP wakelocks, everything is back to normal. Google services is down to like the 3rd or 4th highest battery drain, and the screen is back at the top like it should be.
Now the next problem I'm running into is the CastSocketMultiPlexer getting stuck.

That (castsocketmultiplex) usually associates with casting apps like YouTube and Netflix to the chromecast

Yea, I just haven't figured out how to get that wakelock to not hang. I cast over netflix quite a bit, but sometimes the next morning it'll stick around for a bit. I hate having to constantly reboot my phone.
Oh yea, don't forget the "wakelock-fix" in here to get rid of the system update wakelock. That one is a real MF'r.
Android seems to have a LOT of wakelock problems, and they all seem to be google's fault. It's like every time they update google services they take 1 step forward and 3 steps back.
